Americans of both parties don’t expect the national deficit to shrink, according to a June poll from the Pew Research Center. Seventy percent of respondents said they expected the annual deficit to grow in the next five years, including 80 percent of Republicans and 61 percent of Democrats. Just 11 percent of respondents said they thought the deficit would be smaller in five years, including 9 percent of Republicans and 14 percent of Democrats.

A couple times tonight, Pence has made the case for a conservative, small-government focused GOP. But as evidenced by the crickets on his initial joke at the start of the debate, there just doesn't seem to be much appetite for him in the Trumpified Republican Party. This isn't a surprise really, given he started the campaign already a villain to many Republicans because Trump had blamed him for his defeat because Pence didn't try to block certification of Biden's victory. But Pence finds himself on the edge of the stage tonight because of his low polling level, and there has really been no good polling news for him recently. His horserace numbers are flat or going down and his favorability numbers among Republicans have worsened, with only Christie having more negative ratings. When might Pence actually leave the race? No idea. But in a field full of candidates who are struggling to have a path to winning, Pence is among those with the least signs of hope.

That's a rehearsed line from DeSantis on oil drilling locations if I ever heard one.

The issue of supplying aid to Ukraine as the country remains invaded by Russia has been a major source of contention among the Republican party, even holding up budget negotiations as Congress barrels toward a government shutdown.

A few answers from the GOP candidates at the debate displayed the variety of opinion among the primary field. Christie, who shares the belief of establishment Republicans, spoke about his unrelenting support for Ukraine aid.

“That was the darkest moment in world history when the Soviet Union fell. Listen, everybody, [Putin] wants to put the old band back together, and only America can stop it,” said Christie, who noted that American leadership on the conflict could display strength in other areas of foreign policy.

“Ukraine – that's a green light to China,” Christie said. “They're all connected, Stuart. They're all connected. The Chinese are paying for the Russian war in Ukraine, the Iranians who supply more sophisticated weapons, and so are the North Koreans now as well, with the encouragement of the Chinese.

Christie bashed some of his primary challengers for their opposing views: “the naivete on the stage from some of these folks is extraordinary.”

DeSantis, like the right flank of the party, said he would not embrace continually funding the “territorial dispute.”

“It's in our interest to end this war and that's what I will do as president. We are not going to have a blank check. We will not have US troops and we're going to make the Europeans do what they need to do… Meanwhile, our own country is being invaded.”

Foreign policy isn’t quite dominating this debate, but U.S. policy towards China is a prominent theme, and Ramaswamy is bearing down a lot of attacks on that.

Ramaswamy and Haley had a heated moment on the debate stage over the issue of support for Ukraine – which Haley tied to China. When Ramaswamy argued against support for Ukraine, Haley jumped in, saying that a win for Russia is a win for China, and then accused Ramaswamy of liking China.

There was also the memorable TikTok exchange between the two. Haley sniped at Ramaswamy that "every time I hear you, I feel a little bit dumber for what you say” and that he can't be trusted as he justified his choice to join TikTok after being convinced by influencer and boxer Jake Paul to join despite previously calling it "digital fentanyl." TikTok was created by Chinese company ByteDance and lawmakers have scrutinized the app over security concerns. (Ads for TikTok are also airing on Fox Business Network during commercial breaks.)

Scott also accused Ramaswamy of being ‘bought’ by China. He was likely referencing Ramaswamy's company, Roivant Sciences, announcing 5-years ago that it was partnering with China state-owned investment company CITIC Group Corp

And Pence had a similar, pointed attack: “I'm glad Vivek pulled out of his business deal in 2018 in China -- that must have been about the time you decided to start voting in presidential elections."

It’s worth noting that Haley criticized Trump too on this front, in that case for not pursuing China aggressively enough on a host of issues: “This is where President Trump went wrong.”
